Leak test system for driver-side pyrotechnic airbag inflaters using helium hard vacuum method integrated optional vacuum decay method.


A global supplier of auto components required a fully-automated, production leak test system to test a high volume of air bag inflaters. Customer needed ability to test for gross leaks without helium depletion, with fully automated loading and unloading from conveyor. Test parts include multiple models and sizes, with the potential for parts arriving hot at the leak testing station.


We engineered a turnkey, dual chamber hard vacuum leak testing station that incorporates two independent leak test chambers and associated instruments and tooling.  The two test systems can each be configured to perform helium leak testing at a reject level of 2 x 10-5 atmcc/sec or vacuum decay leak testing at a reject level of 3 x 10-4 atmcc/sec. 

Key Features

  • High sensitivity vacuum decay capability
  • Auxiliary pumping system for high performance and speed
  • Dual helicoptor pick and place material handling system integrated to conveyor
  • Automated part sorting and communication to RFID on pallet
  • Universal grippers for different part models
